HAY-RAKE.

SPECIFICATION forming part of Letters Patent No. 448,145, dated March10, 1891.

Application filed September 25, 1890. Serial No. 366,181. (No model.)

1'0 (0% whom it may concern:

Be it known that I, WILLIAM BYRNE SHARP, a citizen of the United States,residing near D onaldsonville, in the parish of Assumption and State ofLouisiana, have invented certain new and useful Improvements in aHay-Rake;

and I do declare the followingto be a full, clear,

and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention has relation to improvements in rakes for gathering hay,vines, trash, the. and it consists in the construction, novelcombination, and adaptation of devices hereinafter described andclaimed.

In the accompanyingdrawings, Figure 1 is a side elevation of my improvedrake, and Fig. 2 is a top plan view of the same with partsin section.

In carrying out my invention the several parts of the improved harrowmay be constructed of the most suitable material and of a proportionalsize an d weight conducent to a thorough and practical operation.

The wheels G, which are of a form usually employed in this class ofdevices, support a transverse axle-bar S, upon which they are mounted.

Adjacent to the respective spindles of the axle bar I attach theretotwoupright castings or plates F, which are respectively arranged asuitable distance apart to receive between them the longitudinal bars Bof the frame, which are mounted 011 fulcrum-pins journaled in aperturesin the said castings. These bars 13 are respectively provided at asuitable point in their forward portion with inwardly-directed lateralbars 0, which are attached to or formed integral therewith and areadapted to receive pedal-pressure to throw the rake out of operation,and it is obvious that, if desired, a single transverse bar may beemployed in place of the two lateral branches.

The pole or tongue A, which is attached to the axle bar midway of thelength thereof and which extends forwardlytherefrom, may

be of any preferable construction suitable to the requirements placedupon it.

The drivers seat D is mounted upon and attached to three supporting-armsa, b, and c, which are attached to and rise, respectively,

from the pole and the axle-bar, formingatripod support upon which theseat rests, thus leaving a space below the seat for the free playof arearwardly-extending pitman branch of the operating-lever, presently tobe described.

Adjacent to the rear end of the frame-bars B and upon the under sidethereof I attach journal-castings T, which receive the ends of thetransverse shaft 0, in which are fixed the radially-exten dingraking-teeth P.

Fixed upon the ends of the shaft 0 are collars U, and formed integralwith and extending radially from these collars at diametrically-oppositepoints are two l-ugs N, which are adapted to be engaged to fix thetoothshaft, as will be described, and which, if desired, may be formedintegral with the said shaft.

Upon the upper side of the frame-bars B and slightly in rear of theirfulcrum-points I attach thereto two upwardly-extending castings d, whichare provided with journal-apertures to receive a rock-shaft R, forapurpose to be described. This rock-shaft R has fixed upon it at pointsadjacent to its ends and midway of its length castings or plates e,which are secured by bolts or otherwise to a transverse strip ll, ofwood or other suit-able material.

Keyed or otherwise fixed upon the outer ends of the rock-shaft R andsecured thereon by suitable means are crank-arms V, which, if desired,may be formed integral with said shaft.

The links K, which have one end bifurcated and pivotally attached to theends of the crank-arms V, are provided at their opposite ends with aneye, as illustrated, which is pivot-ally secured upon a lateral lugprojecting outwardly from the sliding bars L, which are secured to therespective bars 13 by means of straps f. These bars L, which are movablein the straps and are provided at their inner ends with a lug-stop t,are provided at their opposite or rear ends with outwardly-extendinglateral portions, from which depend lugs M, which engage the lugsN ofthe tooth-shaft and serve to fix the same in an operative position.

Formed integral with and rising from the middle casting e of therock-shaftis a plate g,

to which is pivotally attached the rear end of a link E, the forward endof which is pivotally attached to the lever E at an intermediate pointin the length thereof. This lever E is fulcrumed upon a pin, whichextends laterally from one side of the pole, as illustrated.

In operation, when the lever E is pushed forward the bar His raised andthe rock-shaft R turned, which raises the crank-armsV and pulls thelever K and rod L forward, which movement releases thelugs of thetooth-shaft and allows the said shaft to revolve in its bearings. Whenit is desired to resume raking, the pedal-pressure is removed and thelever pulled back, when the toothshaft will again be fixed.

Having described my invention, what I claim is 1. The combination, withthe axle supported by wheels, the frame fulcrumed thereon provided inits forward portion with a lateral pedal branch, and the transverseshaft carrying raking-teeth journalcd on the rear end of the frame andprovided at its ends with radial oppositely-directed lugs, of thetransverse rock-shaft also journaled on the frame, the crank-arms fixedon the ends of the rock-shaft, the lever-arms K, pivotaily connected tothe crank-arms, the sliding rods L, pivotally con 11 ected to thelever-arms and provided at their rear ends with depending" lugs adaptedto engage the lugs upon the tooth-shaft, and the lever connected withthe rock shaft and adapted to turn the same, all adapted to opcratesubstantially as specified. V

2. The combination, with the main frame mounted upon an axle supportedby wheels and the transverse shaft carrying raking-teeth journaled onthe rear end thereof and having at its ends the radialoppositely-directed lugs, of the transverse rock-shaft journaled on theframe, the crank-arms fixed on the ends of the rock-shaft, the leverarms K, pivotally connected to the crank-arms, the sliding rods L,pivotally connected to the lever-arms and provided at their ends withdepending lugs adapted to engage the lugs upon the toothshaft, and thelever connected with the rockshaft and adapted to rock the same, alladapted to operate substantially as specified.

In testimony whereof I affix my signatn re in presence of two witnesses.
